A seller who makes a mistake in calculating [the total amount due] – unintentionally gives the buyer more or less change [than he is due]; [in this case] should he give [the buyer] the remainder [of the change] or [just] keep it?

If a person had amassed immense wealth made up of trading in haraam, and then repented to Allaah [from that], is it then permissible for him to perform hajj using this wealth, or donate to charity from it, or [even] get married or build a masjid using it?
